Oil pan seal or front profile gasket. Smoking perhaps you have some piston ring wear or valve seals gone.

What causes heaps of smoke on start up , usually cold but goes once operating temperature?Smoke colour is more whitish than oil coloured so is fuel related!

It helps to indicate what vehicle you have , which engine is fitted and the mileage it has done when posing your questions.
No it is not fuel related but very likely engine oil and valve stem related.

The most likely problem is that the valve stem seals are leaking instead of sealing and when you park the car for a decent length of time (as overnight) the oil in the cylinder head drains down via the bad seals into the cylinders and builds up.

When you start the car you will get instant smoke from the exhaust and oil smoke will linger (unlike steam).. It will keep smoking until most of the excess oil has been burned up but oil will continue to slowly leak into the cylinders while driving and will be burned up quickly and cannot accumulate until you shut down the engine again and leave the car again for hours.

Stand behind the car after it has been sitting for a while and check the emissions. Oil smoke is very distinctive in smell and it lingers.

No oil in engine

8000 over is not good. You lose some oil to what is called "blow by". This is when oil pushed by the rings around the pistons. This is a slow process but over time you could lose a bit and not notice any smoke. Also over time oil breaks down when not changed often causing a lot of it to stick to enternal parts of the engine which could be why you didnt get a light. Just some thoughts, sorry about your troubles

I have a Mitsubishi IO 1998. After moving slowly for a while (40mins) in traffic, the car exhaust smokes (blue smoke). When I get out of heavy traffic and drive fast, the smoke goes away completely an

sound to me like it may need the head gasket replacing, check for the following, oil in the coolant, coolant in the oil, leaks of oil from the head, not the rocker cover, check your spark plugs for oil, if it is not the head it could be oil contamination in the cylinders above the pistons. hope this helps

Too much smoke coming from the exhaust

chk your PCV valve. If faulty it will allow oil to be sucked up and burned. Its the critter stuck into the valve cover and has a rubber hose on it. Good

luck, Ned It's an easy fix and inexpensive. So not to panic.

Loss of engine moter oil

Check the Seal around the Oil Pan Drain Plug. If this Seal is Missing or Warped it will slowly leak oil.
